Inspecting structures
by ramana.kumar＠gmail.com 27 Jan '16

Is there a way to look at the contents (i.e. signature) of a structure without opening it? (I suppose you could just open it then call a lot of PolyML.Compiler.forgetXXX, but that's quite tedious) Also, is it possible to retrieve the long path of an identifier in scope? Something that will, for example, take the rev in scope and say that it came from List. Finally, what about searching for an identifier that would come into scope if you opened some structures?

polyc and poly --script
by rene.neumann＠in.tum.de 24 Mar '15

Hi, two completely orthogonal questions/remarks for PolyML 5.5.1: 1.) When building PolyML with '--with-system-libffi' the '-lffi' part is missing in the linker line in polyc. 2.) Is it somehow possible to see if an ML file is run via 'poly --script' or as a standalone executable? Because for the one the logic has to be wrapped in 'fun main ()', and for the other it should not :). (Ie, what I want: if is_script then main() else () ) Thanks, Ren? -- Ren?

What has happened? but it was a false alarm: my make file was wrong for other reasons and the absence of PolyML.Compiler.printTypesWithStructureName was not relevant. No doubt there are good reasons why this variable has been withdrawn. Regards, Rob.

Isabelle/ML IDE

Dear friends of Poly/ML, or Standard ML in general, Isabelle2013-2 is now available from the usual mirror sites: Cambridge (UK) http://www.cl.cam.ac.uk/research/hvg/Isabelle/ Munich (Germany) http://isabelle.in.tum.de/ Sydney (Australia) http://mirror.cse.unsw.edu.au/pub/isabelle/ It is mainly an environment for interactive and automated theorem proving, but the integration of Isabelle/ML into the Prover IDE makes it suitable for general Standard ML development (potentially in teaching scenarios). After downloading / unpacking / running the main application of Isabelle/jEdit, the Documentation panel on the right-hand side gives quick access to Examples, notably src/HOL/ex/ML.thy for some Isabelle/ML basics. The manual on Isabelle/jEdit in the same panel provides further details on the IDE, which is based on the jEdit text editor. Makarius

polyc

I have a couple of comments and a query about polyc (which seemed particularly attractive on Cygwin, where there seems to be quite a long list of libraries you need to know about if you are going to call the linker directly). The comment is that the help text is a bit misleading as it has more functionality than just compiling and linking a source file, e.g., you can pass it the name of an object file and it will link it with libpolymain and libpolyml. The query relates to the fact that polyc doesn?t do anything with LD_RUN_PATH (or DYLD_LIBRARY_PATH on Mac OS). Am I right in thinking that libpolyml will now always be statically linked so that you no longer to need to tell the dynamic linker where to find it? (For Poly/ML versions 5.5 and earlier the ProofPower makefiles that I am updating used to create an executable that linked libpolyml dynamically.) Regards, Rob.
